The Chicago Design System
Content CreationOgilvy gave the City of Chicago a new identity that extends its four-star flag with a fifth star for citizens, made freely downloadable for public and department use.
Case in 60 seconds
Chicago's many government departments and campaigns were visually fragmented, and the city wanted an identity that felt inclusive and owned by citizens.
Chicago's four-star flag is a symbol residents already love, so the identity could grow from it rather than replace it.
Add a fifth star, as an extension of the flag rather than a change to it, to represent citizens and to be shared with them.
Ogilvy built a design system for the city's departments and made the branding downloadable so citizens and businesses could use it too.
The source reports no direct metrics; a linked third-party article estimates the system could save the city up to $10 million a year by unifying department design.

Why Ogilvy's strategy worked
- 1
Extending a beloved existing symbol, the four-star flag, rather than replacing it lowered the risk of public rejection.
- 2
Making the fifth star represent citizens gave the identity civic meaning beyond a government logo.
- 3
Allowing citizens and businesses to download and use the branding turned adoption into a public act.
- 4
A single system across many departments promised coherence and, per a third-party estimate, cost savings.
